I wanna run a tonneau but cant decide if i should spend the 60 dollars for one? Or make one outta the plywood i have in my garage?!

For the amount of fabrication time you'd spend making the wooden tonneau cover, I wouldn't even bother. $60 is a decent chunk of change, but that custom cover's going to be a weekend's work if you want it to look nice. Check out the classifieds for used ones. I've definitely seen them before.
